Tom Cruise battles to save Earth in 'Oblivion.'

As Criticwire's Matt Singer humorously points out, the Hollywood pipeline currently holds two sci-fi films about lone survivors on post-apocalyptic Earths -- and both star Scientologists. We've got trailers for both -- "Oblivion," starring Tom Cruise, and M. Night Shyamalan's "After Earth," starring Jaden and Will Smith.

In "Oblivion," out April 19, Cruise is Jak (not to be confused with "Jack Reacher"), a surface drone repairman who discovers a mysterious woman (Olga Kurlyenko) in a crash-landed pod. Martin Freeman and Melissa Leo also star. Watch both the first and second trailer below.

In "After Earth," out June 7, the two Smiths play a father and son who must explore a long-evacuated planet following an aircraft crash. It will be Shyamalan's follow-up to 2010's catastrophically reviewed, 3-D retrofitted "The Last Airbender."
